Pain control is
Pain can be controlled by a number of therapies including, drugs, surgery, acupuncture, exercise, hypnosis, and even thought distraction
Burn victims can be distracted by allowing them to engage in illusory virtual reality. Their brain scans show differences in pain perceptions.
Gate-control theory of pain:
Pain messages travel on one set of nerve fibers in the spinal cord containing pain gates
• Other kinds of sensory messages go through another set of fibers
The fibers carrying pain messages contain pain gates, which are open when pain is felt
• The non pain fibers can Close the pain gates to stop the sense of pain
• This is why other touch sensations (rubbing the area that hurts or icing it, for example)
can partially block the sensation of pain.
Kinesthetic sense is
the system for sensing the position and Movement of individual body parts
• Relies on receptor cells located throughout your muscles & joint
• One’s leg “falling asleep” is a disruption of the kinesthetic sense
• when you’ve held your leg in the same position for so long that the nerve temporarily stops transmitting kinesthetic information. It is almost impossible to walk smoothly until the link reestablished.
Vestibular sense is
the system for sensing body orientation & located in the semicircular canals of the inner ear
Relies on fluid in the canels
• Spinning in circles disrupts the fluid making one dizzy
